Patent 7741353 was granted and assigned to Los Alamos National Security on June, 2010 by the United States Patent and Trademark Office.
Lead-free primary explosives of the formula (cat)Y[MII(T)X(H2O)6-X]Z, where T is 5-nitrotetrazolate, and syntheses thereof are described. Substantially stoichiometric equivalents of the reactants lead to high yields of pure compositions thereby avoiding dangerous purification steps.
